We unfortunately stopped shipping our "complete" C9 Classic Light Sets (the sets with bulbs and cords in one package) with our traditional glass bulbs due to the frequency with which bulb breakages occurred in transit. As a result, we've transitioned all of our C9 Classic Light Sets to use our high-quality polycarbonate Dura-Bulbs.
That said, we will always sell our C9-sized light strings and 25-count boxes of glass C9 bulbs separately, so you can achieve the same end effect as the complete light set, just without the fancy flip-top box, and some assembly required, as it were.
What you'd be looking for on our website is the E17 (C9) Classic Light String (in Two-Tone Green) and our C9 Classicolor 25 Count boxes of bulbs (in Classic Mix).
